Quick answer
Short answer
Report the loss immediately, then apply in person with a statement regarding the lost passport, citizenship evidence, photo ID, a new photo, and fees. Once reported, the passport is permanently invalid even if you find it.
Search once, then report
Reporting is irreversible. Do a genuine search first, then report without delay, because the report is what unlocks the replacement path.
Expect a first-time-style application
Replacements are in person with originals. If your trip is close, this becomes an urgent case immediately.
